Please email the Organiser, complete the online entry form or sign up to the Facebook event to reserve a map.


A one hour score course, with control sites worth between 10 and 50 points, mostly, but not exclusively according to how far away they are. You will be given a choice of three answers – mark the correct one when you see the control.

This is a control visiting event! Circling answers at controls you have not visited, on the off chance you get it right, is cheating. Answers must be marked in race time.

Your score will be reduced by 2% of the points scored for every minute or part minute late.

League Scoring

The leading man and woman will score 100 points, second place 99 etc. In addition, your score will be increased by a multiple depending on your age and sex, and the resultant points used in the same way for a handicap competition.

This year, we will have a special series t-shirt/technical top (to feature the Central Line stations where events are located) for the winners of each of the Mens, Women’s and Handicap leagues.

Map & Terrain

The map is 1:10,000, with streets, paths and open areas marked. It will be printed on waterproof paper, with the clues on the back.


Results will be available after the event at

Equipment & Safety

You are advised to bring a torch and compass, as well as a pen to mark your answers. We hope to use electronic timing, so bring your own dibber if you have one. Light coloured clothing for extra visibility is advised.

Aprés Run

Join your fellow orienteers for a friendly drink, food and a chat and please support our host pub for this Race. The Railway Bell offers a range of food (including Thursday steak specials) as well as a range of beers and ciders on tap and in the fridge.

Swell 2018/19 – Epping South
Mar 10 @ 10:30 am – 12:00 pm

Event Overview

Orienteering in the southern section of Epping Forest, London, E11.  There will be courses suitable for both beginners and experienced orienteers.  Any queries contact the Organiser (see above).

Forest orienteering event with a range of courses (“colour-coded” according to length and difficulty) which forms part of SWELL 2018-19.  Courses to suit all ages from under 10’s to over 80’s. Adult beginners with a running background may prefer “Orange” or “Light Green” courses. For children under 10, “White” or “Yellow” courses will be best suited. Older juniors should enter “Orange” or “Light Green” depending on experience.

Mapped Area

The map will extend south of the event centre, with the start and finish (within c. 50 m of one another) around 500m walk from the event centre.

The longest courses (Blue and Brown) will travel as far south as Hollow Pond. The northernmost part of the map overlaps in part with the map from our Epping Walthamstow Forest event in November 2016. The rest of the map was last used in April 2013.

Map: Epping South 1:10,000.

Mixed deciduous woodland and forest.


Largely flat, a mixture of open land and dense forest with an extensive path network, but with enough detail to make it a fair navigational challenge.


Entry forms will be available at the event on the day. It will also be possible to complete your registration form prior to the event on this page, beginning mid February – although you should pay your entry fee on the day.


Course Name Approx Distance Technical Difficulty Suitable for
Brown 8.5km 5 – Highest Brown Courses are very physically demanding and have a very hard navigational difficulty. They are for experienced orienteers only.
Blue 6.2 km 5 – Highest Blue Courses are a longer, more physically demanding course in comparison to the green. The distances are more varied between controls and the course attracts experienced orienteers.
Green 5.okm 5 – Highest Green Courses are used mostly by experienced under 18’s and adults wanting a short but challenging course with a very hard navigational difficulty.
Short Green 3.5 km 5 – Highest Short Green Courses are used mostly by adults wanting a shorter but challenging course with a very hard navigational difficulty.
Light Green 3.7 km 4 Light Green Courses are ideal for improvers as the navigational difficulty begins to increase and uses simple contours and ‘point’ features.
Orange 3.0 km 3 Orange Courses progress to basic use of the compass and route choice. They are ideal for novice adults or experienced youngsters.
Yellow 2.2 km 2 Yellow Courses  use simple linear features like paths, walls and streams. They are mainly used by under 12’s and family groups.
White 1.5 km 1 – Easiest White Courses are very easy with all controls on paths. They are mainly used by 6-10 year olds and family groups.

Electronic Punch

EPS-SI on all courses. Dibber hire £1.00 (free hire for juniors).

Safety details

Please note that the Green, Blue and Brown courses will include road crossings, with the busier of these timed out (controls on either side of pedestrian crossing). For the other crossing, a control will be situated near to the pedestrian crossing. All roads are marked as out of bounds other than at specified crossing points and competitors are urged to take care at these crossings.

Full leg cover is strongly advised. First aid cover will be available from the event centre while the nearest Accident & Emergency department is at Whipps Cross Hospital, E11 1NR.

Competitors are urged to show courtesy to other forest users.


We will aim to have results published on the web ( as soon as possible after the event.
